Try this:

this.coolPhone = new JsSIP.UA(configuration);
this.setUAEvent();
this.coolPhone.start();
setUAEvent(ua) {
this.coolPhone.on("newRTCSession", (e) => {
  console.log("new rtc session", e);
  const session = e.session;
  session.on("progress", (message) => {
    console.log("progress session ", message.response.status_code);
    if (message.response.status_code === 180) //RINGING EXAMPLE
    {
        //put your code here
    }
  });
}
